These
earrings were part of another production line, a series based on sea shell
forms produced 1986 - 1992. Originally made in sterling and in gold filled,
later using niobium. Niobium is one of the reactive metals; one of its
properties being, that under certain conditions, it can be colored by
sending an electrical current through the metal. In October of 1987 a
pair of earrings like the ones shown above were used on a model on the
cover of Glamour magazine.
